Speaking to Howard Stern earlier this week, Rogen shared a story in which Bieber was allegedly rude to him.

"Someone came to the door and was like, 'Justin Bieber wants to meet you'," Rogen said, adding that when he agreed and went outside his dressing room, Bieber acted as if Rogen had asked to meet him.

"What the f**k, I don't want to meet you! Don't act all nonplussed to meet me. I didn't want to meet you," he said of his thoughts meeting Bieber. "I was like, 'He's a little bit of a motherf**ker. Whatever. He's a bit of a d**k'."
